Explanation

Cisco ACI (Application Centric Infrastructure) uses a two-tier leaf-spine physical topology, based on the Clos network architecture. Leaf switches (access layer) connect directly to servers, storage, and other endpoints. Spine switches (aggregation/core layer) interconnect all leaf switches in a full-mesh fashion. Every leaf connects to every spine, and no direct leaf-to-leaf or spine-to-spine connections exist. This design provides predictable, low-latency, any-to-any connectivity with a maximum of two hops between any two endpoints. The APIC (Application Policy Infrastructure Controller) manages the entire fabric and applies policy across all nodes.
